Just cant win

So,
Over a year ago I tried making soundboard apps. They are simple to do and rather popular. Mine were always rejected due to using copyrighted material.
But other people have gotten tons of soundboard apps into the Marketplace, some of the same ones and sounds I did, after I was rejected.

I tried another one, and it was again rejected for the same reason! I just can not win. THe people reviewing the apps are just so inconsistent!

Did you distribute the copyrighted material in the app itself? It's possible the approved ones are loading it from an external stream and not storing locally, therefore Microsoft isn't liable. Or something.
